## Summary description

Rittal AS 4051.683 insulated ferrules for conductors, made of copper with polypropylene (PP) insulation in white. Designed for 0.5 mm² conductor cross-section, 12 mm length and 2.9 mm outer diameter. Supplied in a pack of 500 pieces, they provide reliable wire termination, improved contact surface and protection against fraying in control cabinets and electrical installations.

## Long description

Rittal AS 4051.683 insulated copper ferrules are termination sleeves designed for reliable connection of 0.5 mm² conductors. Each ferrule combines a tin-plated copper tube for conductive contact with a polypropylene (PP) insulating collar in white, providing a solid crimp surface, improved contact quality and protection against strand fraying. The ferrules are 12 mm long with a 2.9 mm outer diameter and are supplied in a pack of 500, suitable for repetitive wiring tasks in control cabinets and general electrical installations.
Advantages
The combination of a conductive copper core and a PP insulated collar ensures consistent crimping results and durable electrical contact. The white insulation aids visual identification and neat wiring runs. The 12 mm length gives sufficient insertion depth for secure crimping on 0.5 mm² conductors while the 2.9 mm outer diameter matches common crimp ferrule tooling. Supplied in a bulk pack of 500, these ferrules reduce handling time and are convenient for panel assembly and maintenance work.
Suitable for
Terminating single-strand and multi-strand conductors with 0.5 mm² cross-section
Crimping with manual or ratchet crimp tools designed for insulated ferrules
Wiring and rework inside control cabinets, distribution boxes and terminal strips
Batch wiring tasks where consistent, repeatable terminations are required
When it may not be suitable
These ferrules are specifically sized for 0.5 mm² conductors; they are not suitable for significantly larger or smaller conductor cross-sections. For applications requiring heat-shrink insulation, corrosion-resistant alloys beyond tin-plated copper, or extreme environmental sealing, alternative termination solutions should be considered.
Key specifications
Conductor cross-section compatibility: 0.5 mm²
Length: 12 mm
Outer diameter: 2.9 mm
Material (tube): copper with tin plating for improved contact
Insulation material: polypropylene (PP), white
Packaging quantity: 500 pieces per pack
How to use
Strip the conductor to the appropriate length so that the bare conductor can be fully inserted into the ferrule tube. Insert the conductor until it seats against the insulation collar, then apply a compatible crimping tool centered on the metal sleeve. Use a tool suitable for insulated ferrules to achieve the correct crimp profile and tensile strength. After crimping, visually inspect the termination to ensure there is no exposed strand fraying and that the insulation collar is undamaged. Insert the crimped ferrule into the terminal or connector and fasten according to the connector manufacturer's instructions.
What to consider before purchase
Confirm conductor cross-section is 0.5 mm² to ensure compatibility
Verify your crimping tool supports insulated ferrules of this length and diameter
Consider the required insulation color coding and whether white meets your wiring standard
Ensure bulk pack quantity (500) matches your project scale and storage needs
Usage recommendations
For consistent results, use a calibrated crimping tool rated for insulated ferrules and perform sample pull tests during production or installation. Store the ferrules in a dry environment to avoid contamination of the tin-plated surface and keep the pack sealed until use to maintain cleanliness.
